Siv lub tshuab aluminium profile extrusion muaj ntau cov kauj ruam xws li kev teeb tsa, kev hloov kho, kev sim khiav, kev ua haujlwm, tu, thiab kho. Txawm hais tias nws yuav zoo li nyuaj, koj tsuas yog yuav tsum ua raws li cov lus qhia. Txawm li cas los xij, ua tus neeg teb xov tooj, koj yuav tsum paub txog cov qauv tshwj xeeb ntawm lub tshuab extrusion uas koj ua haujlwm nrog, yog li koj tuaj yeem tswj cov txheej txheem extrusion kom raug thiab ua haujlwm ntawm lub tshuab kom raug. Muaj ntau hom tshuab extrusion, thiab thaum lub ntsiab lus tseem ceeb ntawm kev khiav hauj lwm sib txawv, lawv kuj muaj qee qhov sib xws. Niaj hnub no, cia peb mus dhau cov kauj ruam ua haujlwm thiab cov ntsiab lus tseem ceeb ntawm kev siv lub tshuab aluminium profile extrusion kom meej.
Ib. Kev npaj ua ntej tsav tsheb
1. Rau cov yas siv hauv extrusion molding, cov khoom siv raw yuav tsum ua kom tau raws li qhov xav tau kom qhuav. Yog tias tsim nyog, yuav tsum tau ua kom qhuav ntxiv. Tsis tas li ntawd, sieve cov ntaub ntawv kom tshem tawm cov clumps thiab mechanical impurities.
2. Xyuas seb cov dej, hluav taws xob, thiab roj hauv cov khoom siv puas ua haujlwm zoo, xyuas kom cov kab dej thiab roj av tsis muaj kev cuam tshuam thiab tsis muaj paug, thiab xyuas seb lub tshuab hluav taws xob puas zoo li qub. Xyuas kom lub tshuab cua sov, tswj qhov kub thiab txias, thiab ntau yam twj paj nruag ua haujlwm tau zoo. Khiav lub tshuab pabcuam ntawm qhov ceev tsis muaj kev thauj khoom kom pom tias lawv ua haujlwm li qub. Pib lub tshuab nqus tsev twj tso kua mis ntawm lub tshuab sizing thiab xyuas seb nws ua haujlwm zoo. Lubricate tag nrho cov zawv zawg qhov chaw ntawm cov khoom siv. Yog tias pom muaj teeb meem, kho lawv raws sijhawm.
3. Nruab lub tshuab taub hau thiab sizing lub tes tsho. Xaiv lub tshuab taub hau specifications raws li hom thiab qhov loj ntawm cov khoom. Nruab lub tshuab taub hau raws li hauv qab no.
2. Pib lub tshuab
1. Koj tuaj yeem pib lub tshuab thaum qhov kub thiab txias tau ruaj khov. Ua ntej pib, koj yuav tsum rov kho cov bolts ntawm lub tshuab taub hau thiab extruder flange kom them rau qhov sib txawv thermal expansion. Thaum tuav lub taub hau bolts, ua raws li tus qauv kab pheeb ces kaum thiab siv zog sib npaug. Thaum zawm cov txiv ntseej flange, xyuas kom qhov nro yog ib puag ncig; txwv tsis pub, cov khoom yuav xau.
2. Txhawm rau pib, thawj nias lub pob 'Npaj rau Pib', tom qab ntawd khawm 'Start'. Maj mam tig lub hau ntswj ceev hloov lub pob kom pib lub hau ntswj ntawm qhov ceev tsawg. Maj mam nce qhov nrawm thaum ntxiv cov khoom me me. Ua tib zoo mloog rau lub ntsiab lub cev muaj zog ammeter thiab lwm yam ntsuas ntsuas, thiab kho cov khoom noj raws li xav tau. Rau ib tug ntxaib-ntsia hlau extruder, siv lub metering feeder ntxiv cov khoom sib npaug thiab ntawm qhov sib xws.
3. Thaum cov khoom siv los ntawm qhov tuag yog ib qho zoo thiab cov yas zoo, koj tuaj yeem txuas ntxiv nrog rub thiab shaping. Plastication yog txiav txim los ntawm kev paub dhau los, feem ntau yog raws li cov khoom zoo li-nrhiav rau qhov chaw glossy, tsis muaj impurities, tsis muaj foaming, hlawv, los yog discoloration. Thaum nias lub extrudate los ntawm txhais tes, nws yuav tsum grind mus rau ib tug zoo theem yam tsis muaj burrs los yog tawg thiab muaj ib co elasticity, uas qhia tau hais tias zoo plasticization. Yog tias plasticization tsis zoo, kho cov ntsia hlau ceev, chim, thiab lub taub hau kub kom txog thaum nws ua tau raws li qhov yuav tsum tau ua.
4. Thaum lub sij hawm extrusion ntau lawm, tsis tu ncua xyuas tag nrho cov txheej txheem tsis raws li qhov yuav tsum tau ntau lawm thiab sau rau hauv cov txheej txheem cav. Tshawb xyuas cov khoom profile raws li cov qauv zoo, thiab tam sim ntawd daws txhua yam teeb meem uas tshwm sim.
3. nres lub tshuab
1. Tso tseg cov khoom noj. Thaum cov yas hauv lub extruder raug thawb tawm tag nrho thiab cov ntsia hlau raug nthuav tawm, tua lub hwj chim rau lub thoob thiab lub taub hau, thiab nres cua sov.
2. Tshem tawm lub hwj chim rau lub aluminium profile extruder thiab auxiliary tshuab kom nres cov ntsia hlau thiab cov cuab yeej pab.
3. Qhib lub flange txuas lub tshuab taub hau thiab tshem tawm lub taub hau. Ntxuav lub phaj tuag thiab tag nrho cov khoom ntawm lub taub hau. Txhawm rau kom tsis txhob ua rau lub ntsej muag sab hauv ntawm lub taub hau, siv cov txhuam hlau los yog cov ntawv hlau los ntxuav cov khoom seem, tom qab ntawd siv cov ntawv xuab zeb tshem tawm cov yas daig hauv, txhuam nws, thiab siv cov roj siv roj los yog cov roj silicone los tiv thaiv xeb.
4. Rau kev ntxuav lub taub hau thiab lub thoob, tom qab tshem lub taub hau, rov pib lub tshuab tseem ceeb, ntxiv cov khoom siv nres (los yog cov khoom crushed), thiab ntxuav cov ntsia hlau thiab lub thoob. Nyob rau lub sijhawm no, cov ntsia hlau yuav tsum khiav ntawm qhov ceev (ib ncig sr / min) kom txo tau hnav. Thaum cov khoom noj khoom haus tso tseg tag nrho hauv av rau hauv cov hmoov thiab extruded, compressed cua tuaj yeem tshuab ntau zaus los ntawm cov khoom noj thiab cov pa tawm kom tshem tawm cov pellets thiab hmoov ntxiv. Tom qab paub tseeb tias tsis muaj cov khoom seem hauv lub thoob, txo cov ntsia hlau ceev kom xoom, nres lub extruder, thiab tua lub zog loj thiab lub ntsiab dej txias valve.
5. Cov khoom muaj kev nyab xeeb yuav tsum nco ntsoov thaum extruding aluminium profiles suav nrog hluav taws xob, cua sov, txav cov khoom siv kho tshuab, thiab tuav cov khoom hnyav. Lub rhiav extrusion yuav tsum muaj lifting cov cuab yeej rau kev txhim kho thiab dismantling hnyav qhov chaw xws li lub tshuab taub hau thiab ntsia hlau los xyuas kom meej kev ruaj ntseg.
